Abstract
Device for dispensing a pulverulent product having a reservoir unit (100) connected on the one hand, to an air expulsion system (200) and on the other hand to a dispensing head (300) provided with a dispensing orifice (310). The reservoir unit (100) has a reservoir (110) having substantially the form of a hollow cylinder, with a distal opening (111), a proximal opening (112), and a metering passage (113) connecting the distal and proximal openings (111, 112), a one-way valve (115) being positioned between the metering passage (113) and the distal opening (111), the proximal opening (112) of the reservoir (110) forming a filling cone which tapers towards the metering passage (113) to facilitate filling of the metering passage (113) with a dose of powder.
